had shriveled and many leaves had dropped. Plat I yielded 127 

 grams of shelled beans, Plat II 123 grams, and Plat IV 157 grams. 

 Tlie five succeeding crops were harvested in flower, while the leaves 

 were still green. Tlie absolute and relative growths made on the 

 different plats are shown in Table V. 



It can be scon that the growth of the bush beans averaged, with 

 allowance for the probable error, at least 5 per cent better on the 

 soils Containing carbonate of lime. 



Crt)p B from the four plats was analyzed alone, crops D and F were 

 analyzed together, using a composite sample made up of equal parts 

 of the two crops. The whole plant above ground was used for 

 analysis, stems, flowers, and leaves being fuiely ground up together. 

 In Table \T arc given the percentages of the elements in the carbon- 

 free ash and in the dry substance of the plants from the four plats.
